ALLEN PARK, Mich. (AP) - Reggie Bush has moved a big step closer to returning to play for the Detroit Lions. Bush practiced Wednesday, a few days after missing a game with a banged-up left knee. He would give the Lions a much-needed boost offensively Sunday against NFC North-leading Chicago because Nate Burleson, their No. 2 receiver, needs surgery after breaking his arm in a car accident. Bush didn't practice last week until Friday, when the team said he participated on a limited basis. He was inactive for Sunday's win at Washington. The speedy running back was hurt in a Week 2 loss against the Arizona Cardinals after accounting for 191 yards of offense in his Detroit debut to help the Lions beat the Minnesota Vikings.
